Answer:
The necklace will be 4,000 cm long
Step-by-step explanation:
Here we want to calculate the length of the necklace
Mathematically, that would just be the product of the beads and the diameter of each bead
Hence, we have
10,000 * 0.4 = 4,000 cm
If not the answer that I got is 26/57 = [849 x(x= 372.25)]/5
1428•1829=2611812
After that move to the next digit and write the next result below but before you start add a zero on the answer line, multiply the digits 2·8=16, take the last digit (6) and write it in the answer line, carry the first digit (1) and save it for the next calculation, multiply the digits 2·2= 4, add the carried digit (1) to the previous result 4+1= 5, write the result (5) in the answer line, multiply the digits 2·4=8, write the result (8) in the answer line, multiply the digits 2·1= 2, write the result (2) in the answer line, continue this with every digit and for every row you go down add another zero

Answer:
750 × 1/10 = 750/10 = 75
Step-by-step explanation:
The best way to really predict the outcome of multiplying 750 by 0.1 without calculator is firstly, converting the decimal to a fraction to easily do the multiplication in your head.
Since one of the multiplicand is a decimal the products will be much complicated therefore, to convert the decimal number 0.1 to a fraction number we shift the point to the right hand side which simply translate to 1/10. The trick here is the number of times we shift the point will determine the number of zeros the denominator will possess. Assuming we have 0.12 as the decimal, it is required we shift the point twice and the resulting value we become 12/100. If the decimal is 0.123 it is required we shift the point 3 times , the resulting value will be 123/1000. Not the number of times we shift the point will determine the number of zero's of the denominator.
Finally, the 2 multiplicands are now 750 and 1/10 which is more easier to manipulate in our head.
750 × 1/10 = 750/10 = 75( you just cancel the zeros)
